that the persons to he lowered from the burning,` building een clear Window sills and such like projections. 'f Y Normally the crane is in `the position shown in Fig. 1, but in cose ofi/ire it can he entende@ to the position shown in Fig. Q. @n the arm of the crnneG is placed :i fork 11 carrying the bearings for the shaft l2, upon which the drum 13 'for the eoilfoii'` rope is firmly fixed. The shaft 12 has at its one end a crank 14 which has ai pivot 15 upon which the brake cylinders pisen rods' 16 n easily be seen, that byy the arrangement .here f described one can beforehand approximately determine ille speed et which the lowering shell take pince, when ille weight oi the burden to he lowered is known, enel this een he put ai heut 75 kilos. lf theI person he -soniewlnit heavier, the lowering trikes place' quicker, und if the person is only n child, the ,lowering will o1" course linke piece some what slower. 'ilmt end of the shaft 12 which opposite to the crank erin 1i carries Cog-wheel which engages c cog Wheel 23 on the pivot 2, which moreover is inclosecl by the spring box 25.

in order that the spring con roll up the drum 13 the brake cylinders must he 'thrown ont of gear. This is clone thus: The crank erin 14 is noiy firmly lined to'the shaft 12, but the Sheff* has o pziwl Wheel QG, which is inclosed hy the crank 14, ond this hitter has :i spring 'pewl 27 which presses against lhe pewl wheel. llfliile flic iowcring is toking place, she pswl 'will grip behind one of the leer-l1 on the Wheel 26g :incl pue the brake on the coil, while the phwl Wheel during the iwisting een libe-relie iseli es the mwl recefles. The working` of ille inecheni n is ilius easy no nnllersland. in case oi nre n. person places e hell;- sronncl his Weise and 'lizisens ille hoek jso the heil?, ile their lets himself go; es i'he rope is figln'cnefl the nn i 'elle Drake cylinders; seen as the person has reached ihc gronnil :incl token eli' ille heit ille spiral sgfing, which lies heen tightened during the u-ncoiling of the rope again coils it up automatically, as the brake cylinders are now stationary because the pawl glides over the pawl Wheel.

Vhat I claim, and desire to secure by Letters Patent,.is:

, l. -In a-fire escape, the combination of a support, a standard hinged to the sup ort,

an arm pivoted to the lower portion o the standard and provided With a perforated lug, a rod pivoted to the standard and havmg its upper end passing through the perforation inthe lug on the arm, steps on the rod .to limit the tilting movement of the arm, brackets extending from the arm and formed with bearings, a drum shaft supported 1n said bearings, a drum secured to 1 the drum shaft, a secondshaft supported b y the brackets, gears between the latter shaft vand the drum shaft, a spring on the second mentioned shaft to normally wind the drum, a ratchet Wheel on the drum shaft, a crank loosely mounted on the drum shaft, a spring pressed pawl mounted in the crank to engage the 'ratchet Wheel, cylinders pivoted to the arm, pistons mounted in the cylinders, piston rods on the pistons, said piston rods being pivotally connected to the crank, a roller mounted at the upper end of the arm, a cable passing around the roller and the drum, and

operate, means on the pistons for controlling the flow of liquid in the cylinders whereby to regulate the movement of the pistons, a second shaft mounted on the arm, a spring for normally winding the second shatt in one direction, a. gear on the second ,shaft which meshes with the gear on the drum shaft, a roller on the upper end of the arm, and a cable passing around the roller and the drum.
